Description
Technical Field
The utility model relates to the technical field of chemical industry and smelting reaction equipment, in particular to a chemical liquid adding device.
Background
In the production process of chemical industry and smelting products, the following problems are frequently encountered: according to the known amount of one substance, the amount of the other substance participating in the reaction can be calculated, and when the other substance is added, a certain range of requirements are set on the flow rate of the other substance participating in the reaction, and if the amount and flow rate of the added substance participating in the reaction are improper, the problems of product quality reduction, cost increase and the like finally occur. For example: 1. in the process of oxidizing ferrous iron into ferric iron by hydrogen peroxide, and removing ferric iron by hydrolysis and precipitation, when hydrogen peroxide is manually added into a reaction kettle in a barrel-by-barrel manner, the problems of excessive addition and excessive flow, raw material waste, difficult slurry filtration and the like often occur. 2. In the operation process of replacing and removing heavy metals by using common zinc powder, 10% of zinc in the common zinc powder generally exists in the form of zinc oxide, and part of zinc can not only participate in the replacement reaction, but also delay the reaction, and dilute acid can be added to accelerate the replacement reaction and dissolve and recycle the part of zinc oxide. However, when manually adding dilute acid, the instantaneous flow of the added dilute acid is very easy to be too large, so that the pH of the solution is locally too low, and the zinc and cadmium metals in the reaction system are dissolved, so that the solution is indelible.
Generally in the field of chemical experiments, we can achieve stable control and regulation of the volume and flow rate of the liquid feeding process by using specific experimental equipment, such as a burette. Buret and similar liquid adding devices are usually used for containing liquid to be added through a transparent glass tube body, and scales are carved on the tube body, so that the fixed volume addition of the liquid is realized; the bottom of the pipe body is provided with a liquid outlet, and the liquid outflow is controlled through a valve and other mechanisms, so that the flow control of the liquid is realized.
However, in the field of chemical production, a large amount of liquid needs to be continuously added in many cases, the transparent glass container cannot ensure enough strength, and the safety of the glass container cannot be ensured due to vibration caused by stirring when the liquid is added into the reaction container with high stirring strength, so that serious safety accidents are caused when a large amount of liquid leaks in the glass container when the glass container is damaged. Meanwhile, too thick glass container wall can cause reading error increase, and the purpose of volumetric liquid adding cannot be achieved.
Disclosure of Invention
The utility model provides an automatic liquid feeder with adjustable volume and flow, which aims to realize automatic liquid feeding with adjustable volume and flow in chemical production so as to ensure the accuracy of liquid feeding volume and flow in the liquid feeding process.
The technical scheme adopted for solving the technical problems is as follows: the volume and flow-adjustable automatic liquid feeder comprises a liquid storage container 9 and a liquid level scale 5, wherein a liquid pouring hole 8 is formed in the upper part of the liquid storage container 9, a float mark post hole 31 and a liquid adding mark post hole 41 are formed in the top of the liquid storage container, and a pipe hole 15 is formed in the bottom of the liquid storage container; the liquid adding pipe 16 is connected with the pipe hole 15, and the liquid adding pipe 16 is provided with a control valve 11 and a liquid discharge end 13; the float mark post 3 and the liquid adding mark post 4 are respectively inserted into the float mark post hole 31 and the liquid adding mark post hole 41, the lower ends of the float mark post 3 and the liquid adding mark post extend into the liquid storage container 9, the upper ends of the float mark post are limited by a limiting device, and the limiting device can limit the float mark post and the liquid adding mark post to freely slide in the vertical direction only; the lower end of the float mark post 3 is connected with the float 1, the lower end of the liquid adding mark post 4 is connected with a hose 10, a liquid discharge port 17 is arranged at the connecting end of the hose 10 and the liquid adding mark post 4, and the other end of the hose 10 extends to the position of the pipe hole 15 and is connected with a liquid adding pipe 16 in a sealing way; the liquid level scale 5 is arranged in parallel with the float scale rod 3 and the liquid adding scale rod 4, the scale of the liquid level scale rod 5 is preset, the liquid level display line 2 corresponding to the scale of the liquid level scale rod 5 is arranged on the float scale rod 3, the liquid level control line 18 corresponding to the scale of the liquid level scale rod is arranged on the liquid adding scale rod 4, and the sliding of the liquid adding scale rod 4 in the vertical direction can be limited by the positioning device.
The working principle of the utility model is as follows: when the liquid to be added is poured into the liquid storage through the liquid pouring hole, the floater floats upwards, the floater marker post slides upwards under the pushing of the floater, meanwhile, the liquid level display line on the floater marker post moves upwards along with the floater marker post, the liquid level scale is provided with preset scales, and when the liquid level display line moves to a certain scale, the liquid level display line indicates how much volume of liquid exists in the liquid storage. When the liquid is needed to be added, the control valve can be directly opened, and the liquid in the liquid storage can enter the hose through the liquid outlet and is added into the container through the liquid adding pipe.
However, this mode of use is difficult to accommodate in most chemical operating situations and is very cumbersome. For example, the pouring of the liquid needs to be very accurate, and if the liquid is poured carelessly, a part of the liquid needs to be discharged before the liquid can be added. And the chemical process often encounters the condition that continuous intermittent liquid adding is required, at the moment, the liquid adding mode cannot be well adapted, and the liquid adding time is likely to be missed or the liquid adding is likely to be inaccurate.
In response to the above, we can operate in the following manner: the liquid is poured into the liquid storage device, the liquid level display line moves to the corresponding position, and then the liquid adding mark post is pulled upwards, so that the liquid level control line on the liquid adding mark post moves to the required position and is fixed through the fixing device. The scale corresponding to the liquid level display line at this time indicates how much liquid is contained in the liquid reservoir, and the scale corresponding to the liquid level control line indicates how much liquid is not discharged, and the actual liquid charging volume=the scale corresponding to the liquid level display line-the scale corresponding to the liquid level control line. At this time, the control valve is opened again to carry out liquid feeding. After the liquid adding is completed, the position of the liquid level control line can be adjusted according to the new position of the liquid level display line, and continuous intermittent liquid adding can be realized.
Moreover, by adopting the liquid feeder, the liquid storage container does not need to be made of transparent materials such as glass, and the like, and can be made of various materials according to the required strength of the container and the properties of the contained solution, so that the strength, the safety, the freedom degree and the adaptability of the container are greatly improved.
It will be readily appreciated that the float post is not adapted to use a heavy shaft in order to ensure accuracy of the readings.
As a further improvement of the utility model, the positioning device has the structure that: the liquid adding positioning nail is arranged on the liquid level scale and matched with the liquid adding positioning hole, and can move to the liquid level scale and be fixed in the liquid adding positioning hole, so that the liquid adding standard pole is limited to slide in the vertical direction.
The scheme provides a positioner's setting mode, and the characteristics of this scheme are convenient for operate fast and accurate, especially when the circumstances that the continuous intermittent type liquid feeding is needed in the reply, can carry out the liquid feeding location fast. It is easy to think that we can also use other positioning modes, for example, use the fixed clamp to clamp the liquid adding mark post; or the liquid adding standard pole is arranged into an external thread structure, the fixing device is arranged into an internal thread structure matched with the fixing device, and the position of the liquid level control line is adjusted by rotating the liquid adding standard pole.
When the positioning device adopts a structure comprising a liquid adding positioning hole arranged on the liquid level scale and a liquid adding positioning nail arranged on the liquid adding scale and matched with the liquid adding positioning hole, the liquid adding positioning nail can move to the liquid level scale and is fixed in the liquid adding positioning hole, so that the liquid adding scale is limited to slide in the vertical direction, the setting position of the liquid adding positioning hole corresponds to the scale of the liquid level scale, and the setting position of the liquid adding positioning nail coincides with the liquid level control line, so that the reading and the operation are convenient.
As a further improvement of the utility model, the limiting device has the structure that: the liquid storage container comprises a pore plate fixed above the liquid storage container, wherein a floater marker post limiting hole and a liquid adding marker post limiting hole which correspond to the floater marker post hole and the liquid adding marker post hole respectively in the vertical direction are formed in the pore plate, the floater marker post is inserted into the floater marker post hole and the floater marker post limiting hole, and the liquid adding marker post is inserted into the liquid adding marker post hole and the liquid adding marker post limiting hole, so that the function that the floater marker post and the liquid adding marker post can only freely slide in the vertical direction is achieved.
The scheme provides a setting mode of a limiting device, and the scheme is characterized by simple structure. It is of course easily conceivable that other arrangement modes may be adopted, for example, a pulley structure may be arranged on the float post or the liquid adding post, and the limiting device is arranged to be fixed on the support and is matched with a guide rail structure of the pulley structure, so that the function of limiting the float post and the liquid adding post to freely slide only in the vertical direction can be realized.
As a further improvement of the utility model, the liquid adding pipe is provided with an exhaust pipe which is communicated with the liquid adding pipe and has an upward opening. When the liquid adding device is used for adding liquid such as hydrogen peroxide, the hydrogen peroxide is easy to decompose in the liquid storage container to generate oxygen, and in the liquid adding process, part of oxygen can enter the hose and the liquid adding pipe in the form of bubbles, so that liquid adding is easy to be unsmooth, and the pipeline can be blocked when the pipeline is thin. This scheme we set up the ascending blast pipe of opening through the intercommunication on the liquid feeding pipe for the gas in the liquid feeding pipe can be through the blast pipe exhaust, thereby realize that the liquid feeding is smooth and easy. It will be readily appreciated that in order to prevent liquid from escaping through the vent tube during rapid filling, the vent tube needs to be of a certain length.
More preferably, the exhaust pipe is communicated with the liquid adding pipe outside the control valve. If the exhaust pipe is arranged on the inner side of the control valve, when the control valve is closed after the liquid adding is finished, part of liquid possibly remains in the liquid adding pipe on the outer side of the control valve and cannot be discharged, and the situation that the liquid adding precision is low or the liquid in the pipe is deteriorated or corrodes the pipeline valve when the solution which is not added is added by misoperation or the liquid in the pipe is not used for a long time can be caused, so that the exhaust pipe can be communicated with the liquid adding pipe on the outer side of the control valve, and the residual liquid in the liquid adding pipe can still be discharged out of the pipeline when the control valve is closed.
As a further improvement of the utility model, the liquid storage containers have equal cross-sectional areas at any height. The purpose of adopting the constant cross section liquid storage container is convenient for the setting and the reading of liquid level scale, and when the cross section area of liquid storage container at arbitrary height is equal, the interval of unit scale on the liquid level scale is also equal to the setting of scale of being convenient for also be convenient for the estimation of scale value simultaneously when the reading.
As a further development of the utility model, the liquid discharge end can extend below the liquid surface to be added to the container. When the added liquid is an easily-decomposable substance (such as hydrogen peroxide), the liquid discharge end of the liquid adding pipe must extend below the liquid level in the reaction kettle.
When the above scheme is adopted to add the easily-decomposed liquid, the liquid discharge end stretches into the position below the liquid level of the container, the liquid in the container flows at a high speed under the action of the stirring device, resistance is formed to the outflow of the liquid, and at the moment, the plane where the end face of the opening of the liquid discharge end is positioned and the horizontal plane are arranged at a certain angle (more than 0 DEG) and the opening faces the flowing direction of the liquid in the container. Thereby enabling the liquid to flow out smoothly.
As a further improvement of the utility model, the liquid adding pipe is also provided with a flowmeter so as to facilitate accurate monitoring and adjustment of flow in the liquid adding process.
The beneficial effects of the utility model are as follows: 1) The automatic liquid adding according to the set liquid adding volume and liquid adding flow is realized without human intervention, and the labor intensity of workers is reduced. 2) The liquid level display line on the float mark post can accurately display the volume of the maximum dischargeable liquid in the liquid storage container, the liquid adding positioning nail of the liquid adding mark post is aligned and fixed with the positioning hole on the liquid level scale, the volume of the maximum unreleasable liquid in the liquid storage container can be accurately displayed, the material metering of the added reaction is accurate, the adding volume and the flow are adjustable as required, and the damage caused by excessive or insufficient adding of the reaction material and deviation of the adding flow from the optimal range due to the randomness of manual operation is avoided. 3) The special adjusting mode is convenient for coping with the condition of continuous intermittent large-scale liquid adding in chemical production. 4) The liquid storage container does not need to be made of transparent materials such as glass, and can be made of various materials according to the required container strength and the properties of the contained solution, so that the container strength, safety, freedom degree and adaptability are greatly improved. 5) Convenient operation, easy manufacture and convenient popularization in industry.
